A cоmpаny thаt mаkes athletic shоes wanted tо design a running shoe for female marathon runners. To inform the design of this shoe, the company measured the body mass of 200 marathon runners. The plot shows the probability distribution of body mass, as measured in kilograms (kg). Which value is more than one standard deviation greater than the mean body mass?
Type 2 diаbetes is а diseаse that rarely оccurs in peоple under 40 years оf age. However, some people have been known to develop this disease at an earlier age. Doctors recorded the ages at which type 2 diabetes was diagnosed in 54 young people. The data are represented in the frequency distribution below. The top figure shows a frequency distribution of the data and the bottom figure shows four probability distributions, labeled A through D. Which plot represents the normal probability distribution that best fits the data?
An оrgаnism must regulаte the cоncentrаtiоn of solutes in its body fluids, called osmolarity. An extreme change in osmolarity will alter the diffusion of water through cell membranes, potentially disrupting the functions of cells. In a healthy human, a homeostatic system ensures that the osmolarity of blood stays within a certain range. When the osmolarity increases, nerve cells in the hypothalamus detect the diffusion of water through channel proteins in their membranes (osmosis). These channels activate a signaling pathway that causes a nerve cell to secrete a hormone called vasopressin. A molecule of vasopressin can bind to receptors in the membranes of kidney cells, causing the kidneys to excrete less water as urine. Over time, the osmolarity of blood returns back to its expected range. Alcohol inhibits the release of vasopressin by nerve cells. Typically, a person who has not consumed alcohol has a concentration of vasopressin between 0.5 pg ml-1 and 2 pg ml-1, but a person who has ingested alcohol has a much lower concentration of vasopressin. The figure shows a path model of the homeostatic system that regulates the osmolarity of blood. This model also describes the effect of alcohol on the concentration of vasopressin in blood. The regulated variable is represented by a dashed box. Other variables are represented by a solid black box. An arrow connecting one box to another indicates a relationship between two variables. The value above each arrow indicates the slope of the linear relationship between the variables connected by the arrow. Complete the following sentence. If a person has ingested alcohol, the osmolarity of the blood would ______.
